यदि (y=(a+7)x+(a-12)) मूल बिंदु से गुजरती है, तो इसकी ढाल क्या होगी?
If (y=(a+7)x+(a-12)) passes through the origin, what will be its slope?
Explanation opens after your attempt
C. (19)
Concept
To pass through the origin, (a-12=0). Thus (a=12) and the slope is (a+7=19).
Why this answer is correct
The correct answer is C. (19). To pass through the origin, (a-12=0). Thus (a=12) and the slope is (a+7=19).
Exam Tip
मूल बिंदु से गुजरने के लिए (a-12=0) होगा। इसलिए (a=12) और ढाल (a+7=19) है।
